Bypassing Website Crawl: The Ultimate Guide to Selenium's Emulated Browser

Teach you to use Selenium + proxy IP broken website anti-climbing

Brothers engaged in crawling know that the anti-climbing mechanism of the site is now more and more refined. Today we talk about a tough trick - with Selenium with proxy IP, specializing in a variety of anti-climbing difficulties. This trick can be more useful than the ordinary request header disguise, after all, the browser fingerprints this thing site can not be good to recognize.

Why does your crawler always get caught?

Most sites stare at three key points:Request frequency, IP characteristics, browser fingerprintsThe first thing you need to do is to use the requests library to send a request. Just use the requests library to send requests, it is no different from running naked. For example, an e-commerce site found that the same IP request 50 times per minute, immediately give you a blacklist. This time if you canChange IP every 5 requestsThe success rate is directly doubled when paired with real browser environments.

Selenium+Proxy IP real-world configuration

Let's start with how to stuff proxy IPs in Selenium. ipipgo's is recommended.Dynamic Residential AgentsThe API of their home is easy to fetch IP thieves. Look at the code example:

from selenium import webdriver

proxy = "123.123.123.123:8888" Use the ipipgo extraction interface here.
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server=http://{proxy}')

driver = webdriver.Chrome(options=chrome_options)
driver.get("https://目标网站.com")

Watch out for potholes:You have to test the availability of the proxy IP first, we recommend using the ipipgo provided bySurvival Detection Interfaceto avoid encountering dead IPs jamming the crawler.

Dynamic IP switching of the soi operation

It's not enough to use one agent. You have to do it.IP pool rotationThe first thing you need to do is to change the IP address of the crawler. There is a trick here: the ipipgo API access to the crawler system, every time you start a new browser instance will automatically change the IP. test a recruitment site with this method, continuous collection of 8 hours without being blocked.

The Eighteen Ways of Counter-Detection

It's not enough to just change the IP, you need a full disguise:

1. Randomize mouse trajectory (don't draw straight lines)
2. Simulation of a real person scrolling a page (fast and slow)
3. Randomized wait time (0.5-3 seconds variable)
4. With ipipgo.Geolocation BindingFunctions to match IP and browser time zones

Frequently Asked Questions

Q: What should I do if my proxy IP is slow?
A: Go with ipipgo'sExclusive use of high-speed linesThe latency can be pushed down to less than 200ms. Don't be cheap and use a shared pool, the speed really pulls the crotch.

Q: How do I break the CAPTCHA when I encounter it?
A: Two thoughts: ① use ipipgo'sFixed Outlet IPCooperate with the coding platform ② automatically change IP after triggering the verification code + clear cookies

Q: How do I test if the proxy is working?
A: Visit http://ip111.cn这类检测网站 and focus onThree key parameters: Consistency of IP address, time zone, and DNS resolution location

Lastly, I would like to remind the brothers that they have to look at the agency services.IP purityI'm not sure if I've ever had a problem with that. I've used certain small factory proxies before, and the IPs were long ago marked as data centers by major websites. Now I've been using ipipgo's residential proxy, and the success rate is steady at over 92%. The key is their homeNationwide coverage of 300+ cities, which is particularly smooth when doing geographic collection.
